We recently proposed a new approach for the real-time monitoring of particle therapy treatments with goal achieving high sensitivities on range measurement already at limited counting statistics. This method extends Prompt Gamma (PG) timing technique to obtain PG vertex distribution from exclusive Time-Of-Flight (TOF). It was previously shown, through Monte Carlo simulation, that an original data reconstruction algorithm (Prompt Time Imaging) allows combine response multiple detectors placed...

Microbeam radiation therapy (MRT) is a radiotherapy technique combining spatial fractionation of the dose distribution on micrometric scale, X-rays in 50–500 keV range and rates up to 16 × 10 3 Gy s −1 . Nowadays, vivo dosimetry remains challenge due ultra-high fluxes involved need for high-spatial-resolution detectors. The aim here was develop striped diamond portal detector enabling online microbeam monitoring during synchrotron MRT treatments. detector, 550 µm bulk monocrystalline...
The MoniDiam project is part of the French national collaboration CLaRyS (Contrôle en Ligne de l’hAdronthérapie par RaYonnements Secondaires) for on-line monitoring hadron therapy. It relies on imaging nuclear reaction products that related to ion range. goal here provide large area beam detectors with a high detection efficiency carbon or proton beams giving time and position measurement at 100 MHz count rates (beam tagging hodoscope). High radiation hardness intrinsic electronic properties...

Introduction: We propose a method for prompt-gamma verification of proton range during particle therapy, called Prompt-Gamma Energy Integration (PGEI). Method: This is based on the measurement total energy deposited in set detectors located around patient. It particularly suited case high-instantaneous beam intensities, like pulsed beams extracted from synchro-cyclotron. GATE simuations were used to evaluate sensitivity, and dedicated scintillators tested as function intensity. Results...
